Chemical composition and antioxidant activity of the essential oil from leaves of Corymbia citriodora Hook grown in western Cuba

The chemical composition of the essential oil from leaves of Corymbia citriodora Hook. Grown in western Cuba was studied by GC-FID and GC-MS. A total of 72 volatile compounds were identified in the essential oil. The composition was dominated by oxygenated monoterpenes (92.4%), whereas citronellal (35.6%), isopulegol (27.6%), ISO-isopulegol (12.2%), and b-Citronellol (10.4%) were the most abundant constituents in the essential oil. Furthermore, we assessed the antioxidant properties by using three in vitro assays: 2,2-diphenyl-1-picrylhydrazyl test, ferric reducing antioxidant power and lipid peroxidation assays. The essential oil had in vitro antioxidant properties depending on the chosen method. In addition, this effect may be specific due to the chemical components of the oil.
